WlNDOW-SHADE HOLDER.

SPECIFICATION forming part of Letters Patent No. 521,784, dated one 26,1894.

Application filed December 31,1892- Serial No.456,930. (No model.) I

To all whom it may concern."

Be it, known that I, ABRAHAM B. DUNKLE, a citizen of the United States,residing at Steelton, in the county of Dauphin and State ofPennsylvania, have invented certain new and useful Improvements inWindow-Shade Holders, of which the following is a description, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon.

My invention relates to an extension strip, for window shade rollers,the object being to provide a comparatively inexpensive device for thesupport of curtain roller brackets whereby the same strip can be adaptedfor difierent sized windows and varying widths of shades.

My invention consists in the various matters hereinafter described andreferred to in the appended claims.

In the accompanying drawings which illustrate my invention, Figure I isa view in perspective of my improved window shade strip; Fig. 2 isahorizontal section through the same.

In the drawings A represents as a whole, the strip'or bar to which theroller brackets are attached; this strip is extensible,as shown in Fig.1, and is composed as herein shown of two parts a a, each being cut awayfor about half its thickness between the points 1 and 2 so that whenplaced together the parts a will lap, and together, in thickness justequal the thickness of the main body of the strip.. These parts aresecured to each other and guided one'upon the other by means of bands oftin or other suitable metal, one of said bands 0, being secured to theend of the lap-' ping part of each section and partially or whollyencircling the other section. By this means the sections are permittedto slide apart a limited distance, the bandsc, forming stops to preventtheir separation. At a short distance from the outer end of each sectiona vertical recess 01 is out, these recesses being adapted to receive theshanks e of the bracket By making this recess entirely within the bodyof the strip an outer wall for the recess d is formed, and through thispart of the strip outside the recesses, nails or other securing meansmaybe driven tofasten the strip in place. In order to hold the shank ofthe roller bracket in place I have herein shown an angle plate of zinc,tin or other suitable metal, this plate g.being secured to the strip,

and extended out over the recesses so as to hold the shanks of thebracket.

It willat once be seen that a strip constructed in accordance with thepresent in vention possesses many advantages. Especially is this true inthe manufacture, as the recess d necessitates but a cut of a machine,and, this recess being formed wholly within the strip as shown, a backand sides are formed for holding the bracket in place, thusnecessitating in addition, but a support for the bottom and front of thebracket. This is supplied by the angle plate 9, which, being of tin orzinc as described, is sufficiently resilient to clamp the bracket andaid by its re siliency in holding said bracket in place.

The device is extremely simple and efficient. The recess or groove isformed in the strip at a single cut, but two parts (the strip and theangle plate) are required, and when these are assembled as shown, achamber is formed into which the bracket is readily inserted and asreadily removed, and in which it is firmly held, while the portion ofthe strip between the end thereof and the recess,affords a surfacethrough which a tack may be driven to I hold the strip in place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A support for brackets and the'like comprising a strip provided witha groove formed therein, the sides of said groove from the back to thefront lying in the same line, and a separate plate fitting partly oversaid groove; substantially as described.

2. A support for brackets and the like comprising a strip provided witha groove formed therein and extending to the lower edge thereof, and aseparate plate fitting partly oversaid groove; substantially asdescribed.

3. A support for brackets andthe like comprising a strip provided with agroove formed therein and extending to the lower edge thereof, and aseparate angle plate fitting partly over the face of said groove andextending beneath the same whereby the bracket is held I in place;substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
